In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Homoleptic Copper(I) Alkoxide and Phenoxide Clusters Stabilized by Intramolecular π-Coordination: Tetrameric o-Allylphenoxocopper(I) and Hexameric 2-Methyl-3-buten-2-oxocopper(I), published in 1998-01-19, which mentions a compound: 75732-01-3, mainly applied to copper alkoxide phenoxide cluster intramol stabilized; tetrameric allylphenoxocopper hexameric methylbutenoxocopper preparation structure, COA of Formula: C9H11Cu.
Built-in π-alkene functionalities have been found to yield homoleptic copper(I) phenoxide and alkoxide clusters exhibiting tetrameric cubane- or hexameric ribbon-shaped structures. While tetrameric o-allylphenoxocopper(I) (1) is remarkably stable, retains its structure in solution, and resists carbonylation, hexameric methylbutenoxocopper(I) (2) dissolves in such a way that oxo-bridged copper(I) is retained, whereas π-alkene-copper(I) coordination is destroyed, leaving copper(I) free to accept carbon monoxide as a ligand.
There are many compounds similar to this compound(75732-01-3)COA of Formula: C9H11Cu. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
